period before we got sufficient for the tr1.

we got il into maSseeuite. No words OF

ed had we got very little sugar from our
experiment. AS u matter of fact, how
ever, we obtained just twenty per cent.
more massecuite than we got from a slnl-
lar quantity Of canes passed through our
mill, the return of lnaSSeculte in the one
case being l4.63 per cent. on the weight
of the canes, while the masSecultes Obtain
cd from the same weight of canes by our
mill was 1914 per cent. l am sorry to say
that the S-angerhauSen people omitted to
put i'll "a weighing apparatus. IN spite or
my having warned Mr.. Schultz on the
subject. The consequence was that we
had to subject our cLneS to u great deII OF
handling. and to delay our process while
this handling was going on. The result,

was, I considered, 80 far satisfactory that
it showed us that iii spite of very adverse
conditions diff lsion gives us almost the ex-
act increase over mill returns which | had
calculated rs probable from what | hal

people without diff ;ulty. And finally,
it laid altogether one bugb1ar which has
been prominently brought forward by al
vocates of the mill. | refer to the dispO-
sal of the chips. This was really a serious
matter, for at NOnpdreJ when III full work
We should nave to deal with two tons
of chips every eight minutes, and Mr.:
K0lImann warned me at Aska that this
was by far the most serious difficulty
with which [ should nave to contend.
81 much did | fear this that | seat out
half 4 mile Of wire trNlnway for the pur-
pose Of summing and burning the chips, az
I had seen lone by human labOur ut ASkt.
70 our great relief, however, we found
that our mill, the trash turner Of which
hal been slightly raised, took our chips
readily, aud re-deliHerad them to us Goa
tanning "6hly IS per cent. moisture, and
therefore in u state to form excellent fuel.
They were thrown into o ~ n3EE
furnaces, and as soon as these were got
warm the chips bnrnt readily. Mr. Lew.
eIIyn Jones is Of opinion that we may
now safely count upon this difficulty
having been overcome, though it is pos
sible that some slight modification i'll tie

to refer to, and will then conclude. In
the first place, / was disappointed with
the color Of Our ditfusion juice We used
bush water instead of the beautiful river
water at fAska; but Mr.. Kollmann had
told me we slioull probably tind this
thoroughly filtered by passing through
the 1diffuSers, his idea being that the chips
themselves would take up the impurities
in the water. . l do not know whether
the long exposure to u high temperature
iniuriously affected the juice; probably 1t
did; Q but when it got to our clariier
lott it was not nearly as clear and
bright as / hoped it would be. My second
remark is with reference to the cutters.
We found that the description OF cutter
furnished by the Sangerhausen people
at first would not work at all the cush-
cush being thrown to the edge of .the disk
